The OptrisCamera transport handler allows receiving videos and images from Optris Infrared cameras using the Optris PI Connect SDK. The operator can only operate in push mode. 

Options

  • serialnumber: The serial number of the camera to use. If no serial number is specified, the first free camera will be used. (optional)

Schema

The output of the handler provides the following attributes as a schema. All attributes are optional and can be in an arbitrary order and will be identified by the type (IMAGEJCV, STARTTIMESTAMP) or name (flagstate).

NameTypeDescription
imageIMAGEJCVThe current frame of the video stream
starttimestampSTARTTIMESTAMPThe start time stamp of the frame
flagstateSTRING

Current state of the camera flag. The flag is periodically (~12s) closed to re-calibrate the camera sensor which results in a short delay (~500ms).

Possible values are:

  • fsFlagOpen: The camera flag is opened and new images are sent
  • fsFlagClose: The camera flag is closed and the last image before closing is sent
  • fsFlagClosing: The flag is currently closing
  • fsFlagOpening: The flag is currently opening
  • fsError: An error occured

Example

This example shows how to grab a thermal video from an optris camera (16-bit 1 channel), transform it to a grayscale RGB image, and display it in a window. Temperatures are mapped as a linear function from 10.00°C -> 0 (black) to 40.00°C -> 255 (white).
